Kunwisa ndeimwe chikamu chinokosha chekutarisira munda, nokuti muzhizha, masikirwo emasikirwo emiti (kwete kunyange yakanyanya kunyanyisa kufanana nenyuchi kana zviyo) hazvina kukwana. Munda wega wega anoronga, achishandisa mikana iripo. Kana pane dziva kana tsime riri pedo naro, saka hapana chikonzero chekutakura mabhakiti emvura kunwisa munda, zvakakwana kutenga pombi yepamusoro.
Nheyo yekushanda kwepombi yepamusoro pemvura yekudiridza
Ichi chigadzirwa chivako chinosanganisira:
- mvura inobata hose (metal tube);
- iyo pombi chaiye;
- rubber hose;
- kunwisa muto kana sprinkler.
Inogona kushandiswa kukwevera mvura kubva pakadzika isingapfuuri mamita 10, ndiko kuti, pombi yepamusoro yakakodzera yekudiridza bindu kubva kune rwizi runyararo, rakadzika zvakanaka, dziva, gungwa kana gomba.
Zvinokanganisa zvikuru zvavo zvinosanganisira kusuruvara kwavo. Izwi iri rinogona kuderedzwa nekuvanza chikwata chiri muimba yekumusoro kana nekuisa pamateti erubha. Sezvinyorwa zvinyorwa zvinonyanya kukosha kwekushanda. Pashure pezvose, kutanga kutsirira, unongoda chete:
- Pasi pemvura inopinza mvura mukati megungwa;
- kuisa pombi padanda rakaoma, rakaoma (somuenzaniso, asphalt);
- shandisai mvura yekudiridza;
- simba.
Imwe pfungwa yakanaka mukushandiswa kwemapombi iwayo ndiko kukwanisa kuvhara uye kutendeuka musoro, pasina kutya kutya moto.
Ndezvipi zviri pamapombi zvekudiridza?
Iyo pombi yepamusoro pane imwe mukati inogona kuva:
- Vortex. Kufambisa kwemvura kunoitika nekubatsirwa kwemajasi akaiswa paanisis, iyo inotenderera nekuda kwesimbi yemagetsi. Icho chinopesana nehuwandu hwakadzika hwekutsvaira (kusvika kusvika 4 m). Inogona kushandiswa chete mumvura pasina kusachena.
- Centrifugal (self-priming). Mukugadzirisa, yakafanana chaizvo nemhepo inotenderera, inongova nevhavha yemhepo, iyo inoshandiswa mvura kumvura shure kwekuzadza makamuri mupombi. Une huwandu hwekudzivirira hukuru (kusvika kusvika 10 m), hushoma hunoziva kuvepo kwezvisina kunaka mumvura.
Kubva pahutu hwepombi idzi, vortex inokurudzirwa kuti ishandiswe mumadziva nematsime asina kudzika, uye centrifugal yemvura yemasikirwo.
Nzira yekusarudza pombi yepamusoro yekudiridza?
Chisarudzo chemidziyo iyi yekudiridza bindu chinofanira kunge chakavakirwa pane zvinotevera:
- Kudzika kwekutsvaga. Icho chinonyanya kubva padziva kubva kwauri kuronga kutora mvura, uye yechipiri - paukuru hwebindu. Munyaya iyi, tinofanira kufunga nezvehuwandu hwe "1 m vertically = 8 m horizontally". Kubva pazviri, zviri nyore kuverenga kuti iwe unoda zvakadzama sei kuderedza pasi.
- Kureba kwemvura kana musoro. Hazvifaniri kunge zvisingasviki kure nemakiromita kubva panzvimbo yepombi kusvikira kumucheto kweruwa ruchadikanwa kunwa mvura.
- Kubudirira. Izvi ndizvo zvinotarisirwa nemamita akawanda
inogona kutyaira nepombi. Nokuda kwekudiridza, chiyero ichi hachifaniri kunge chiri pasi pe1 m3 paawa. - Engine injini. Nekudiridza kwenzvimbo huru, pane mamwe majekiti ane simba anotevera, kunze kwekudiridza kunotora kwenguva yakareba.
- Kureba kwepipeline. Kuti uite izvi, zvakakosha kuwedzera urefu hunodikanwa hwekuvhara mvura nemvura uye yepaji yekudiridza.
Pakati pemidziyo yekudiridza, pombi dzemapurisa dzevakadaro vakaita seAl-co, Awelco, Grundfos, Wilo neGiriki vakazviratidza zvakanaka.
Pasinei nokuti iyo inowanzo mumirayiridzo yekushandisa kune iyo yakashandurwa inonzi iyo dzimba inopesana nemvura, uye kushandiswa nguva dzose kwechikwata kunobatsira kuvaka chinyorwa chayo (chitupa kana kukateura). Izvi zvichakuponesa kubva pakudiwa kwekutakura panguva yemvura.
